An HLA‐based framework for simulation of large‐scale critical systems

Abstract

SUMMARYEvaluating the dependability of large-scale critical infrastructures is a very difficult task that requires sophisticated modeling practices and experimentation environments/infrastructures. In particular, simulation of complex distributed systems require the integration of several different simulation tools and real-time prototypes or emulated subsystems, which have to inter-operate in a coordinated way. This paper presents a framework integrating simulation and emulation-based subsystems, which is able to provide greater realism of the scenario under test. However, integrating simulation and emulation is a challenging issue because of the different time domains and to the communication overhead between the different time models, as well as to the large number of involved entities. Therefore, the high level architecture has been used to perform integration in a robust and standardized scenario. A cloud-based virtualization platform has been adopted in order to reproduce complex system architectures on an elastic and adaptive locally controlled testbed.

A context‐aware and intelligent framework for the secure mission critical systems

“…Such frameworks help to simplify the development and optimization of different systems. Some mission-critical middleware is discussed in the following: Adaptive and reflective middleware systems (ARMS) [12] provides a framework to simplify the development, optimization, and integration of middleware in real-time systems. Distributed object computing (DOC) middleware [10] is composed of self-governing software objects, distributed throughout a wide range of networks to support a variety of middleware-based services.…”

“…Conventional mission critical frameworks lack facilities to adapt tactical situations and suggest confident information to enhance situation awareness for a timely response 10,11 . Most of the frameworks for mission‐critical systems are based on the request/response paradigm such as high‐level architecture (HLA) 12 and distributed interactive simulation 13 . Association or withdrawal of multiple resources is cumbersome due to the tight coupling of middleware services and communication standards.…”

Advances in modelling and simulation for big‐data applications (AMSBA)

“…In , Ficco et al offer a simulation/emulation framework that combines different subsystems, integrated by HLA, capable of very realistic representation of the behavior of complex heterogeneous distributed computing architectures. The authors built a cloud‐based virtualization platform to reproduce complex system architectures on an elastic and adaptive locally controlled testbed.…”

An Open Architecture Framework for Electronic Warfare Based Approach to HLA Federate Development

“…At this time, the lack of EW M&S reusability, scalability, and interoperability has been degrading its usefulness [4]. Several studies have produced framework for M&S-based system, but they have not been dealing with EW M&S problem domain [5]. In order to solve these problems, "Open Architecture Framework for Electronic Warfare (called OAFEw)" was developed that can achieve the reuse and interoperability of EW M&S lifecycle [4].…”

“…The basic concept of OAFEw is that EW M&S software components are to be reassembled to suit the user's needs with its building blocks defined in the common Reference Conceptual Model and rules governing all stages through an EW M&S lifecycle [4]. Now, High-Level Architecture/Run-Time Infrastructure (HLA/RTI) is already widely used in the field of defense M&S. Also, related research is actively proceeding [5,6]. In addition, the US DMSO (Defense Modeling Simulation Office) mandates that all defense M&S developed after 2000 are executive on RTI basis.…”
